The purpose of this research is to analyze the efficiency of an induction motor controller, using space vector pulse width modulation (SVPWM) in open loop. With a constant torque of 1.5 Newton per meter. It is carried out by applying the mathematical model, the formulas for commutation times and space vectors in Simulink taking into account the maximum and minimum values of operation by applying the SVPWM method to generate the trigger signal in the Insulated Gate Bipolar Transistor bridge. (IGBT's), implementing the model in the Lucas Nulle practice module, taking the power data and calculating the efficiency to compare with the mathematical model and validate, resulting that the controller efficiency varies according to the switching speed of the semiconductor block, with the operation of a motor of 0.37kW and 1KW at a speed of 200rpm the efficiency of the controller reaches a value of 72.67% in the physical model that consists of 6 IGBT's of 1 kVA and 69% in the simulated model presenting an error of 5% and a switching speed of the IGBT's of 248.641ms.
